Answer 2

Only Nitrogen forms 78 per cent of the air.

• Earth is the only planet in the solar system that has a habitable atmosphere.
• The exosphere, thermosphere, mesosphere, stratosphere, and troposphere are the five primary layers of the Earth's atmosphere.
• The gaseous blanket that surrounds the earth not only houses the oxygen we breathe but also shields us from the sun's heat and radiation ( UV rays), especially the ozone layer in the stratosphere layer.
• The gases in Earth's atmosphere, as per NASA, involves:
• 78 per cent Nitrogen
• Oxygen makes about 21% of the atmosphere.
• 0.93 per cent argon
• 0.04 per cent carbon dioxide
• Water vapour, as well as trace amounts of neon, helium, methane, krypton, and hydrogen.
• With increasing altitude, air pressure falls. The atmosphere is relatively dense at sea level, with an air pressure of around 14.7 pounds per square inch (1 kilogramme per square centimetre).
